Hi all,

I am trying to cut away from the the triangular extrusion up to the OUTER highlighted surface on the side of the extrusion. However, the cut goes all the way through to the opposite side. I do not want there to be any holes in the cylindrical body. Earlier, when I had designed the triangular extrusions in a much more complicated way, I was able to surface cut with no problem. Now however I can't seem to define that I want the closest surface to be the stopping point. The idea is to leave triangular "prongs" on the tube surface.

This is my current method of making the triangular extrusion. Does this have any bearing on the surface cut issues?
